Donald Trump has won the US presidency with a campaign that broke all the rules. Is the stage therefore set for America’s economic policy to take off in an equally unprecedented direction – and should the rest of us be fearful or elated?

These questions cannot yet be answered with any certainty: so far, not much is known about who will take the most important economic posts in the new administration, nor what detailed policies they and the president-elect advocate. But we know enough from Trump’s campaign pledges and the Republican Party’s better-known conventional platform to make some educated guesses.
